I am looking for some insight if anyone has had similar issues.
My new '17 stingray seems to be having engine misfire issues. I encountered it for the first time around the end of April and took it to the dealer who replaced the spark plug that went out in cylinder 4. While my car was misfiring, I was having some sort of leak into the exhaust that would create a big puff of smoke as soon as I would accelerate at times.
Skip forward to after getting it fixed the first time, I could still see smoke coming out the exhaust at times so I knew the exact problem would happen again. Just about 4-5 days later I got another engine misfire issue. This time they replaced a spark plug in cylinder 1. I picked up the car but I am pretty certain that this spark plug issue is just the affect of a cause they cant seem to find since there still is a leak in the exhaust. I have told this to the dealer but they seem to think its not going to happen again.
Actually, I went to another dealer and talked to a mechanic there and he told me the exact opposite of my servicing dealer. One of them is saying that this puff of smoke is normal while one is saying that its not normal. The amount of smoke is good enough to blind the driver behind me if that makes it any clearer.
How should I go about this if the misfire issue comes up a third time?
Furthermore, I also have this really loud noise when I cold start the car and it doesn't go away until it fully warms up and the car is driven for around 10-minutes. I brought this under the dealers attention and they replaced a bolt in the drive support assembly under the guidance of GM engineers. However, that did not fix the issue. It just quietened the noise a bit but its still there. They have now ordered a drive shaft from GM and will be replacing that this week under the guidance of GM engineers. However, they have told me that even this might not fix it.
I am not sure if the issues are connected but its quite annoying to keep taking the car back to the dealership. Especially a car which has less than 7500KMs on it.
I am located in Toronto
